Common questions

What is ECT-32-B and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32 indicates the mailer can withstand 32 pounds of crushing force per linear inch. The 'B' denotes corrugated construction. This rating ensures reliable stacking performance, critical for warehouse operations where boxes are palletized multiple units high, reducing damage rates and customer return costs.
How much assembly time do I save with the one-piece fold-and-tuck design?
Operators can fold and tuck each mailer in 3-5 seconds with no tools, tape, or adhesives required. For a fulfillment team packing 1,000+ units daily, this eliminates labor overhead and material waste compared to traditional setup-box or tape-sealed cartons.
Can these mailers be stacked efficiently on a pallet?
Yes. The compact 6 x 6 x 5" footprint and crush-resistant double-wall construction enable stable stacking of filled mailers 8-12 units high without compression damage. This maximizes truck cube utilization and reduces freight cost per unit.
Are these mailers suitable for fragile items?
Absolutely. The ECT-32-B rating and double-wall protection on the front and sides provide cushioning and impact resistance ideal for small fragile products like glassware, electronics, and cosmetics. The fold-to-lock design also prevents unintended opening during transit.
